    Thanks for the post on available memory with which to work with this
    version of DR.DOS. That's right in line with OS/2's available memory
    too. With OS/2, DPMI, as far as I know, is fine though.

    I'd really like to know if WIN 3 whatever can be run with DR.DOS. And,
    if someone knows, how does DR.DOS fair with QEMM.386?

    Thanks for any information you can share!

    Hi Dan,

    I have used PB3.5 with DrDos 7.03 ever since 7.03 came out. Be sure that the expanded memory manager is emm386.exe not .sys. In the emm386
    config.sys line be sure DPMI is turned off. With DOS loaded high and 4 Tsr's loaded in high memory I have 625K of memory free. When I map
    unused video memory [memmax +v] I get 720K free allowing all my programs to run in the IDE. You can not acheive this with MS Dos.

    As an addendum to the above..in the DR-DOS setup (Memory section) there is a checkable option to use LIM 4 EMS...by default that is NOT checked. Make sure it is!

    I use DR-DOS 7.03 exclusively without any problem for PB in both single tasking and multitasking modes. Without the exact error message it isn't possible to say what the problem is. Make sure you do not have DR-DOS's Himem.sys installed if you are running a 386 and above (emm386 handles that function). Use the DR-DOS setup programme to configure XMS/EMS memory usage and the multi-tasker if you want it. Check out http://www/drdos.org and other links there for advice on various configuration options, patches and utilities.

    If you do not want the multitasking environment, you might want to consider using the Himem.Sys AND Emm386 from Win98/ME. In DR-DOS it gives an (ignorable, non-fatal) error on boot and you achieve piddly MS-DOS levels of available lower memory but if you programme for XMS/EMS you can access all up to 256Mb

    Use MS-DOS? Sounds like DR-DOS 7.03 has problems.

    It is likely to be DR-DOS, not PB, that is complaining about
    unstable memory. What's the error message, exactly?

    Did the EMM386 you're using come with DR-DOS? You might want to
    scan your disk and make sure you're using the DR-DOS EMM386, if
    any, rather than any other versions of EMM386 that might be
    sitting around. Microsoft's EMM386 may well not be compatible
    with DR-DOS.

    If nothing else, you might use PBINST to tell PB.EXE not to look
    for EMS. That should hopefully get you up and running.
